Part of the Case IH Repair Manuals.
Fault codes on the armrest display mean nothing without the tree that decodes them, and the 195-page Case IH 330 service manual PDF (factory number 84257309) is that tree, written for the STX and Steiger Series tractors across two dozen model designations. Transmission, armrest, and instrumentation controller fault codes fill most of the book, each one running from symptom to connector pin to the reading that confirms the failure. Calibration routines for the inching pedal and transmission clutches sit up front, followed by neutral relay, BOC switch, and FNRP pod shuttle faults. Probe a transmission speed sensor and you should see about 3 k ohms at 20 degrees C; the hydraulic fan control circuit reads 5.1 to 7.5 ohms. A tractor parked on a code is acres not covered. Bookmarks and a live text layer put you on the exact fault code in seconds, so your tractor finishes the pass instead of sitting.
